Limits of coherence: Where and why is the transition to discoherence?

This paper provides a conceptual solution to the questions of what causes discoherence and where the limits of coherence might be. Coherence is reinterpreted from the cordus perspective, as being a state when all the particules have synchronised frequencies and phases thereof, i.e. a form of complementary frequency state synchronisation (CoFS). Alternatively coherence can be perceived as a special state of assembly where the particules provide for mutual preservation of the de-energised locations of each other. Cordus anticipates three mechanisms for discoherence. First, a coherent material cannot accept internal shear velocity. Second, higher temperatures lead to decoherence because phonons (internal thermal vibrations) disturb the stability. Third, more complex assemblies of matter are harder to put into coherence, and the complicating factors are expected to be the number of components in the assembly, and the variety of species (simplicity and purity). Accordingly, the upper limit for coherence could be a simple crystal, or perhaps even a virus, with a limited number of species (different molecules or elements), at low temperature. However this is thought to be an optimistic prediction. This model predicts that coherence is already unachievable at the assembly level of the smallest metal grains, mineral crystals, and cell organelles, at ambient temperature. Thus warm macroscopic objects and living creatures cannot be put into coherence or superposition. However there is no problem with having coherent domains within a discoherent body, e.g. molecules that are internally coherent. Single particules, such as electrons, are selfcoherent under any conditions. Edition 1 > Date: Monday, 9 January 2012 > Document: Pons_Cordus_6.0_CoherenceLimits_E1.0.9.doc
